How to turn off the Marionette/gecko driver logs in selenium 3 - selenium

Question

I need to turn off the Marionette/GeckoDriver logging; is there is any way to do that? I've been searching a lot, but I am not getting the proper answer.
The INFO logs were:
1484653905833 geckodriver INFO Listening on 127.0.0.1:15106

How do I turn off this logging?

Answer 1

You can disable the logs by sending them to /dev/null via a system property like so:
System.setProperty(FirefoxDriver.SystemProperty.BROWSER_LOGFILE,"/dev/null");
return new FirefoxDriver();

Answer 2

Working solution on Windows and Linux.
# python 3
# windows
PATH_TO_DEV_NULL = 'nul'
FIREFOX_DRIVER_PATH = 'D:\\path\\to\\geckodriver.exe'
# linux
PATH_TO_DEV_NULL = '/dev/null'
FIREFOX_DRIVER_PATH = '/path/to/geckodriver'
# start browser
driver = webdriver.Firefox(executable_path=FIREFOX_DRIVER_PATH,
service_log_path=PATH_TO_DEV_NULL)

Answer 3

Tried the following code, but didn't work. Seems like a bug in selenium 3.0
LoggingPreferences pref = new LoggingPreferences();
pref.enable(LogType.BROWSER, Level.OFF);
pref.enable(LogType.CLIENT, Level.OFF);
pref.enable(LogType.DRIVER, Level.OFF);
pref.enable(LogType.PERFORMANCE, Level.OFF);
pref.enable(LogType.PROFILER, Level.OFF);
pref.enable(LogType.SERVER, Level.OFF);
DesiredCapabilities desiredCapabilities = DesiredCapabilities.firefox();
desiredCapabilities.setCapability(CapabilityType.LOGGING_PREFS, pref);
WebDriver driver = new FirefoxDriver(desiredCapabilities);
driver.get("https://www.google.com/");
driver.findElement(By.id("lst-ib")).sendKeys("something");
Thread.sleep(2000);
driver.quit();

Answer 4

One option that has worked for some is proposed here, and uses a batch file to pass in command line arguments to the executable. Unfortunately, this oftentimes leaves extra processes open (geckodriver.exe, cmd.exe) and no solution to this next problem has been proposed as of yet...

Answer 5

GeckoDriverService gecko = new GeckoDriverService(new File("c:/selenium/geckodriver.exe"), 4444, ImmutableList.of("--log=fatal"), ImmutableMap.of());
gecko.sendOutputTo(new FileOutputStream("gecko_log.txt"));
gecko.start();
FirefoxOptions opts = new FirefoxOptions().setLogLevel(Level.OFF);
DesiredCapabilities capabilities = opts.addTo(DesiredCapabilities.firefox());
capabilities.setCapability("marionette", true);
FirefoxDriver driver = new FirefoxDriver(gecko, capabilities);

Answer 6

This might be a bit hacky but it can quickly get the job done. Given that you know the exact location of your file and you run your code on Linux you can just cd into that dir and
rm geckodriver.log
ln -s /dev/null geckodriver.log

Answer 7

service_log_path seems to be deprecated in python:
driver.py:77: DeprecationWarning: service_log_path has been deprecated, please pass in a Service object
This worked for me now:
from selenium.webdriver.firefox.service import Service as FirefoxService
from selenium import webdriver
service = FirefoxService(driver_path, log_path='nul') # Disable logs in windows, for linux probably /dev/null
driver = webdriver.Firefox(
service=service
)
